4 # The user-driven targets are:
6 # buildworld - Rebuild *everything*, including glue to help do
8 # installworld - Install everything built by "buildworld".
9 # world - buildworld + installworld.
10 # buildkernel - Rebuild the kernel and the kernel-modules.
11 # installkernel - Install the kernel and the kernel-modules.
12 # reinstallkernel - Reinstall the kernel and the kernel-modules.
13 # kernel - buildkernel + installkernel.
14 # update - Convenient way to update your source tree (cvs).
15 # upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
16 # most - Build user commands, no libraries or include files.
17 # installmost - Install user commands, no libraries or include files.
18 # aout-to-elf - Upgrade an system from a.out to elf format (see below).
19 # aout-to-elf-build - Build everything required to upgrade a system from
20 # a.out to elf format (see below).
21 # aout-to-elf-install - Install everything built by aout-to-elf-build (see
23 # move-aout-libs - Move the a.out libraries into an aout sub-directory
24 # of each elf library sub-directory.
26 # This makefile is simple by design. The FreeBSD make automatically reads
27 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
28 # command line. By keeping this makefile simple, it doesn't matter too
29 # much how different the installed mk files are from those in the source
30 # tree. This makefile executes a child make process, forcing it to use
31 # the mk files from the source tree which are supposed to DTRT.
33 # The user-driven targets (as listed above) are implemented in Makefile.inc1.
35 # If you want to build your system from source be sure that /usr/obj has
36 # at least 400MB of diskspace available.
38 # For individuals wanting to build from the sources currently on their
39 # system, the simple instructions are:
41 # 1. `cd /usr/src' (or to the directory containing your source tree).
44 # For individuals wanting to upgrade their sources (even if only a
45 # delta of a few days):
47 # 1. `cd /usr/src' (or to the directory containing your source tree).
48 # 2. `make buildworld'
49 # 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
50 # 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
51 # 5. `reboot' (in single user mode: boot -s from the loader prompt).
53 # 7. `make installworld'
57 # See src/UPDATING `COMMON ITEMS' for more complete information.
59 # If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
60 # update the legacy support for aout. This includes all libraries, ld.so
61 # and boot objects. This part of build should be regarded as
62 # deprecated and you should _not_ expect to be able to do this past the
63 # release of 4.0. You have exactly one major release to move entirely
66 # ----------------------------------------------------------------------------
68 # Upgrading an i386 system from a.out to elf format
71 # The aout->elf transition build is performed by doing a `make upgrade' (or
72 # `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
73 # by a `make aout-to-elf-install', depending on user preference.
74 # You need to have at least 320 Mb of free space for the object tree.
76 # The upgrade process checks the installed release. If this is 3.0-CURRENT,
77 # it is assumed that your kernel contains all the syscalls required by the
80 # The upgrade procedure will stop and ask for confirmation to proceed
81 # several times. On each occasion, you can type Ctrl-C to abort the
82 # upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
83 # the confirmation steps.
85 # At the end of the upgrade procedure, /etc/objformat is created or
86 # updated to contain OBJFORMAT=elf. From then on, you're elf by default.
